Eppendorf’s new cross-over Centrifuge 5430 R is a microcentrifuge with multipurpose capabilities—it spins tubes from 0.2ml to 50ml and microplates, it has a maximum speed of 30,130 x g (17,500 rpm) and requires 15-inches of bench space. Researchers can now spin 15 and 50mL conical tubes and PCR or ELISA plates directly on a lab bench. Refrigerated Model 5430 R is also equipped with temperature management options to protect samples and save on energy. Eppendorf North America, Inc., 800-645-3050, www.eppendorfna.com
